Afezo Listed by thegentlemen Ransomware Group

On March 1, 2026, Dutch civil engineering firm Afezo B.V. appeared on the leak site of the ransomware group known as thegentlemen. The company, which handles urban sewer systems, road construction, and drinking-water networks across Amsterdam and the Zaanstreek, is claimed to have had internal files exfiltrated during a ransomware attack.

What's Publicly Reported from Reporting

Public reporting indicates that Afezo B.V. was listed on the extortion portal operated by thegentlemen. The listing references the company’s website and a ZoomInfo profile but does not publicly disclose the exact number of affected individuals. Available details confirm that internal company files were taken; the precise volume and full contents remain known only to the attackers and the victim at this time. The incident follows the group’s standard pattern of stealing data before encrypting systems and then demanding payment to prevent publication.

Why This Matters for You and Your Family

When a local infrastructure company like Afezo suffers a breach, ordinary families can be exposed. Customer records, supplier contracts, employee payroll files, and project documents often contain names, addresses, phone numbers, email accounts, and sometimes bank details of residents whose homes or neighborhoods were part of sewer or road projects. If those records are released, anyone whose information was stored by the company could face increased risk of identity theft, phishing, or harassment. Even if you never directly hired Afezo, public-works projects frequently pull in data from surrounding households through permitting, billing, or service requests.

Credential leaks from such incidents frequently cascade into account takeovers that affect personal email, banking, and online shopping accounts used by you or your children.

The Doxxing and Identity-Chain Implications

Ransomware leaks rarely stop at one company. Once internal files appear on a dark-web leak site, other criminals scrape the data and combine it with information from earlier breaches. A single email address or phone number found in Afezo’s documents can be linked to your social-media handles, children’s gaming usernames, school records, or family photos. This creates an identity chain that makes targeted doxxing or harassment far easier. Gaming accounts belonging to teenagers are especially vulnerable because kids often reuse passwords or email addresses that also appear in family-related business files.

Thegentlemen’s Publicly Known Track Record

Public reporting attributes thegentlemen with emerging in late 2024. The group has claimed responsibility for attacks on a range of mid-sized organizations, including manufacturing, logistics, and local-government contractors. Their typical playbook begins with initial access gained through phishing or compromised remote-desktop credentials, followed by extensive exfiltration of sensitive files over several weeks. They then deploy ransomware and later post samples of stolen data on their leak site if the victim does not pay by the stated deadline. Extortion pressure is applied both through data publication threats and, in some cases, direct contact with affected customers or employees.

What to do

• Run a DoxxScan to map every link between your handles, emails, phone numbers, and real identity, then use the cleanup to remove what you can.
• Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next leak that touches your family is caught in hours rather than months.
• Rotate any password you ever used at Afezo or related suppliers anywhere it has been reused, and switch on 2FA through an authenticator app instead of SMS.
• Cover the household with DoxxScan family coverage that extends to dependents and children’s gaming accounts that can chain back to the same address or parent email.
• Let remediation specialists handle takedown requests across data brokers and leak sites for you while you focus on securing day-to-day accounts.
